The company doesn’t claim to trace Monero transactions, they claim to have tools that help visualize Monero transactions on the blockchain.

Monero’s recipient on the blockchain is hidden by using one time stealth addresses, and the amount is hidden with range proofs.

However, the sender is merely obfuscated and each UTXO is coming from one of multiple (11) stealth addresses. With these visualization tools and extra information (i.e. you sent Monero to the victims wallet), you might be able to guess when they made a withdrawal.
